Guys, Thanks for all the help. Looks like I'm going to give it a crack and clean/ freshen up my SU carbs. Thanks again!

Yes, they definitely look like Hitachi Flat-top carbs. I hear there are a lot of issues with the flat-top carbs. I have a 73 and the previous owner swapped the flat-top carbs out for SU carbs. I'm glad he did.

Hello, I am fairly new to SU carbs and have a few quick questions. I have a 1973 Datsun 240z with 3 hole SU carbs. I was driving the car the other day and noticed that I was loosing power at WOT. I got the car home and it was idling low and died out on me in the driveway. I popped the hood open and noticed that the rear carb was leaking from the lower nozzle head or hose onto my header (I don't want to burn my car down). I also noticed that the float bowl was loose (loose meaning I can take my hand and rock it back and forth)and some fuel was coming out of the top float nipple. Sound like I have a couple of issues here with the float and/or lower jet nozzle/nozzle hose. Below are a few newbie questions I have. 1. Should the float bowl be loose? I can take my hand and rock it back and forth. 2. Should the overflow nozzles have a hose to direct the fuel away from the header? 3. Are the nozzle hoses hard to come by? I did a quick search and couldn't find anything online. Where I can get some replacement hoses? 4. How hard is it to remove the jet and is there a seal or gasket that can be replaced here? 5. How hard is it to completely remove the carb from the car? Thanks, Dan

Thanks Zed Head!

So how can I identify what year 280zx this came out of? I just check the ignition module and found that it is an E12-80. So after digging around it looks like this is out of a 1979-1981 280zx N/A. Can someone please confirm that this is correct? Also does anyone know what would be the recommended spark plugs and spark plug gap for this distributor? Thanks! Dan

I've purchased my car a few years ago and never really did anything to the engine except for an oil change and new spark plug wires. I've decided to upgrade the ignition system by upgrading it to an electronic ignition and when I pulled my dizzy cap off to check the points system I found that it was already converted over to an electronic setup. I would like help identifying which electronic system is installed. See photos below. Looks to me that this may be an 280zx distributor swap. Can someone help me identify what I have installed? BTW...My Z is a 1973 240z I would like to upgrade the coil, as I have seen that a "flame thrower" coil would be a good upgrade. There's two options here, a 1.5 ohm and a 3.0 ohm coils. Which one should I get? Spark plug wires are new which I got from Datsun Spirit. Also what spark plug would you guys recommend? Any help would be much appreciated! Thanks Dan!

Looking for a clean center console for my 1973 Datsun 240z. I currently have three and neither fit the bill. Looking for one that has no cracks or missing/damaged areas. Thanks!

Jfa.series1 thanks for the help. I just wanted to confirm I was on the right track. I'll look for the red wire with the open female connector for the map light tomorrow. Thanks again for your help!

ok after looking over all the wiring. It turns out that I have two blue wires with female connectors that are unplugged. One should be to the blower motor power source. The second one has me stumped, could it be to the radio? The radio harness has three wires which includes two speakers and a blue wire. There's a red with blue striped wired that is loose. Could the red with blue stripped wire go to the other blue female connector? This still leaves the question as to where does the map light connect too? Thanks, Dan

After looking a this closer looks like the red (+) wire from the blower motor harness is blower motor power source. So where does this go? The only wire I have left over to hook this too s a blue wire (See photo attached)

Hello, First I need some help figuring out where the map light is hooked up too. It looks to me as if the map light red (+) wire goes to the heater blower motor harness which has a red wire as well. Now there's a black (-) wire from the map light that I don't know where it connects too. Can anyone confirm where the black (-) wires goes? I see that the blower motor harness has a black wire with a ground hook but the wire from the map light has a male connector. Thanks, Dan

looks like grannyknot is correct and the wires are in the harness itself and are not connectors like they are shown in the diagram. Thanks for all your help guys! I was worried that my harness was missing these connectors but that's not the case!

Sorry it's a 73 series II 240Z

Hello, I need to some help understanding/locating where these two backup light wires go. They are #39 & 40 on the diagram below. The description on the diagram states they are backup light wires but I don't see where they would be plugged into. #39 - Backup Lights (RB) #40 - Backup Lights (LR) Thanks, Dan
